Add the ability to ignore time-based CRL errors from OpenSSL by
specifying a new configuration parameter, check_crl_strict=0.
This causes the following:
- This setting does nothing when CRL checking is not enabled.
- When CRL is enabled, "strict mode" will cause CRL time errors to not
be ignored and will continue behaving as it currently does.
- When CRL is enabled, disabling strict mode will cause CRL time
errors to be ignored and will allow connections.
By default, check_crl_strict is set to 1, or strict mode, to keep

IEEE Std 802.1X-2010, 11.11 describes that the ICV is separate from the
parameter sets before it. Due to its convenient layout the ICV Indicator
'body part' is used to encode the ICV as well.
IEEE Std 802.1X-2010, 11.11.3 describes the encoding of MKPDUs. In
bullet e) is desribed that the ICV Indicator itself is encoded when the
ICV is not 16 octets in length. IEEE Std 802.1Xbx-2014, Table 11-7 note
e) states that it will not be encoded unless the Algorithm Agility
parameter specifies the use of an ICV that is not 16 octets in length.
Therefore the length calculation for the ICV indicator body part must
take into account if the ICV Indicator is to be encoded or not. The
actual encoder of the ICV body already takes care of the rest.
In practice, this change will remove the ICV Indicator parameter set (4
octets before the ICV value itself) since the only defined algorithm
agility value uses an ICV of 16 octets. IEEE Std 802.1X-2010 MKPDU
validation and decoding rules in 11.11.2 and 11.11.4 require the
receipient to handle both cases of ICV Indicator being included or not.

pretty strange in the loop by clearing the pointer for any non-matching

To prevent a remote peer from getting stuck in a perpetual 'potential

peers and not for potential peers.
Per IEEE Std 802.1X-2010, 9.4.3 (Determining liveness), potential peers
need to show liveness by including our MI/MN in their transmitted MKPDU

When a potential peer does include our MI/MN in an MKPDU, we respond by
moving the peer from 'potential_peers' to 'live_peers'.
If a potential peer does not include our MI/MN in an MKPDU within
MKPDU_LIFE_TIME, let the peer expire to facilitate getting back in sync

The previous commit introduced parameter set error checking. This commit
extends upon that by considering missing parameter sets a failure.
Two checks are added by this commit. First, verify that live peers start
encoding MKA_SAK_USE within a reasonable amount of time after going live

MKA_SAK_USE it continues to do so indefinitely.

The status values returned by mka_param_body_handler.body_rx functions
are currently ignored by ieee802_1x_kay_decode_mkpdu(). If a failure is
detected the KaY should (a) stop processing the MKDPU and (b) do not
update the associated peer's liveliness.
IEEE Std 802.1X-2010, Table 11-7 (MKPDU parameter sets) and 11.11.3
(Encoding MKPDUs) dictate that MKA_SAK_USE (set type 3) will always be
encoded before MKA_DISTRIBUTED_SAK (set type 4) in MKPDUs. Due to
implementation of mka_param_body_handler, the code will always decode
MKA_SAK_USE before MKA_DISTRIBUTED_SAK. When MKA_DISTRUBUTED_SAK
contains a new SAK the code should decode MKA_DISTRUBUTED_SAK first so
that the latest SAK is in known before decoding MKA_SAK_USE.
The ideal solution would be to make two passes at MKDPU decoding: the
first pass decodes MKA_DISTRIBUTED_SAK, the second pass decodes all
other parameter sets.
A simpler and less risky solution is presented here: ignore MKA_SAK_USE
failures if MKA_DISTRIBUTED_SAK is also present. The new SAK will be
saved so that the next MKPDU's MKA_SAK_USE can be properly decoded. This
is basically what the code prior to this commit was doing (by ignoring
all errors).
Also, the only real recourse the KaY has when detecting any bad
parameter set is to ignore the MKPDU by not updating the corresponding
peer's liveliness timer, 'peer->expire'.

If a live peer ever changes its Member Identifier (MI), the KaY
correctly detects a "duplicated SCI" but then proceeds to delete the
peer without deleting the peer's resources (i.e., RxSC, RxSAs, TxSAs).
Note that a remote peer's MI will change if and when an
ieee8021XPaePortInitialize is executed on the remote port.
The solution here is to ignore all MKPDUs containing the new MI until
after the peer (that corresponds to the old MI) expires and cleans up
its resources. After the old peer is removed reception of the next MKPDU
containing the new MI will result in the creation of a new peer with the
new MI.

The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."
When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.
Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

Delay Protect and Replay Protect are two separate and distinct features
of MKA. Per IEEE Std 802.1X-2010, 9.10.1 "Delay Protect, TRUE if LPNs
are being reported sufficiently frequently to allow the recipient to
provide data delay protection. If FALSE, the LPN can be reported as
zero", and per 9.10 "NOTE--Enforcement of bounded received delay
necessitates transmission of MKPDUs at frequent (0.5 s) intervals, to
meet a maximum data delay of 2 s while minimizing connectivity
interruption due to the possibility of lost or delayed MKPDUs."
This means struct ieee802_1x_mka_sak_use_body::delay_protect should only
be set TRUE when MKPDUs are being transmitted every 0.5 s (or faster).
By default the KaY sends MKPDUs every MKA_HELLO_TIME (2.0 s), so by
default delay_protect should be FALSE.
Add a new 'u32 mka_hello_time' parameter to struct ieee802_1x_kay. If
delay protection is desired, the KaY initialization code should set
kay->mka_hello_time to MKA_BOUNDED_HELLO_TIME (500 ms).

Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

It is better not to process a new (most likely repeated) FILS HLP
request if a station retransmits (Re)Association Request frame before
the previous HLP response has either been received or timed out. The
previous implementation ended up doing this and also ended up
rescheduling the fils_hlp_timeout timer in a manner that prevented the
initial timeout from being reached if the STA continued retransmitting
the frame. This could result in failed association due to a timeout on
the station side.
Make this more robust by processing (and relaying to the server) the HLP
request once and then ignoring any new HLP request while the response
for the relayed request is still pending. The new (Re)Association
Request frames are otherwise processed, but they do not result in actual
state change on the AP side before the HLP process from the first
pending request is completed.
This fixes hwsim test case fils_sk_hlp_oom failures with unmodified
mac80211 implementation (i.e., with a relatively short retransmission
timeout for (Re)Association Request frame).

Add interface for drivers to report changes in TX/RX throughput
dynamically to user space. This information can be used by userspace
tools to tune kernel's TCP parameters in order to achieve peak
throughput. The driver may optionally provide guidance on which TCP
parameters to be configured for optimal performance along with the
values to be configured.
The TCP parameters that need to be tuned for peak performance are not
interface specific. Based on the guidance from the driver and
considering the other interfaces that may be affected with the new
configurations, a userspace tool has to choose the values to be
configured for these parameters to achieve optimal performance across
interfaces.
The throughput levels informed by the driver with this event are only
for providing guidance on TCP parameter tuning from userspace. The
driver may change the thresholds used to decide low or medium or high
throughput levels based on several parameters based on the PHY layer
capacity in the current connection, the number of packets being
dispatched per second, or the number of packets pending in queues, etc.
The throughput levels may not be consistent with the actual throughput

Add support for negotiating WNM Collocated Interference Reporting. This

interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

Previously the file permissions for the debug log file were not
explicitly set. Instead it was implicitly relying on a secure umask,
which in most cases would result in a file that is world-readable. This
is a violation of good practices, since not every user should have
access to sensitive information that might be contained in the debug log
file.
Explicitly set sane default file permissions in case the file is newly
created.
Unfortunately the fopen(3) function does not provide such a facility, so
the approach needs to be changed in the following way:
1) The file descriptor needs to be created manually using the open(3)
function with the correct flags and the desired mode set.
2) fdopen(3) can then be used on the file descriptor to associate a file
stream with it.

Previous implementation ended up triggering PMF check for previous
association and SA Query procedure incorrectly in cases where there is a
STA entry in hostapd, but that STA is not in associated state. This
resulted in undesired temporary rejection of the association with status
code 30.
This ended up breaking OWE group negotiation when PMF is in use since
the check for the OWE group would have happened only after this earlier
PMF check and rejection (i.e., the station got status code 30 instead of
the expected 77).
For example, when the AP is configured with OWE group 21 and a station
tries groups 19, 20, and 21 (in this sequence), the first two
Association Request frames should be rejected with status code 77.
However, only the first one got that status code while the second one
got status code 30 due to that issue with PMF existing association
check.
Furthermore, hostapd was continuing with SA Query procedure with
unencrypted Action frames in this type of case even though there was no
existing association (and obviously, not an encryption key either).
Fix this by checking that the STA entry is in associated state before
initiating SA Query procedure based on the PMF rules.

PMKID derivation with the Suite B AKMs is a special case compared to
other AKMs since that derivation uses KCK instead of PMK as an input.
This means that the PMKSA cache entry can be added only after KCK has
been derived during 4-way handshake. This also means that PMKID would
change every time 4-way handshake is repeated even when maintaining the
same PMK (i.e., during PTK rekeying and new associations even if they
use PMKSA caching).
wpa_supplicant was previously replacing the PMKSA cache entry whenever a
new PMKID was derived. This did not match hostapd expectations on the AP
side since hostapd did not update the PMKSA cache entry after it was
created. Consequently, PMKSA caching could be used only once (assuming
no PTK rekeying happened before that). Fix this by making wpa_supplicant
behave consistently with hostapd, i.e., by adding the Suite B PMKSA
cache entries with the PMKID from the very first 4-way handshake
following PMK derivation and then not updating the PMKID.
IEEE Std 802.11-2016 is somewhat vague in this area and it seems to
allow both cases to be used (initial PMKID or any consecutive PMKID
derived from the same PMK). While both cases could be supported that
would result in significantly more complex implementation and need to
store multiple PMKID values. It looks better to clarify the standard to
explicitly note that only the first PMKID derived after PMK derivation
is used (i.e., match the existing hostapd implementation).

The WDS-STA-INTERFACE-ADDED/WDS-STA-INTERFACE-REMOVED events were always
sent to the first BSS instead of the specific BSS that the STA was
connected to in multi-BSS cases. Fix this by using the BSS specific
context pointer.

GCM-AES-256 cipher suite is defined in IEEE Std 802.1AEbn-2011.
If authenticator configured as GCM-AES-256, the distributed SAK will be
256 bits indicated by the GCM-AES-256 ID in the MKA packet.
This patch will make AES Key Unwrap to 32 bytes of SAK when identify the
ID.

Make it clear that the consideration should be only for the IBSS case
and in infrastructure BSS case, PMKID KDE should not be added due to
risks involved with exposing this to stations that do not know the
passphrase.

Ignore unauthenticated encrypted EAPOL-Key data in supplicant
processing. When using WPA2, these are frames that have the Encrypted
flag set, but not the MIC flag.
When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
not the MIC flag, had their data field decrypted without first verifying
the MIC. In case the data field was encrypted using RC4 (i.e., when
negotiating TKIP as the pairwise cipher), this meant that
unauthenticated but decrypted data would then be processed. An adversary
could abuse this as a decryption oracle to recover sensitive information
in the data field of EAPOL-Key messages (e.g., the group key).
